Air Distribution System
From the heating and ventilation unit outlet, the air is directed via air ducts to the various vents, which distribute the air in the cabin.
Floor and defroster vents
There are four floor vents, of which two are for the rear floor. On year model 1988, front floor ducts were added with four separate air vents as well as rear door fans (not illustrated) for demising the rear windows.
There are six defroster vents. Two of these control air to the windscreen and four small vents on the dashboard direct air to the front windows.
From year model 1987, chassis number CH1007949 for left-hand drive cars and chassis number CH1024270 for right-hand drive cars, all defroster air for the side windows is concentrated to the vents in the loudspeaker grills.
Air vents in the facia
There are four air vents in the facia. These can be individually controlled and the direction of air flow can be regulated both vertically and horizontally. The vents in the facia have a control which allows air volume to be continuously controlled.
